Interface VideoListener

All Known Subinterfaces:

SimpleExoPlayer.VideoListener

public interface VideoListener

A listener for metadata corresponding to video being rendered.

Method Summary

Modifier and Type	Method and Description
void	onRenderedFirstFrame() Called when a frame is rendered for the first time since setting the surface, and when a frame is rendered for the first time since a video track was selected.
void	onVideoSizeChanged(int width, int height, int unappliedRotationDegrees, float pixelWidthHeightRatio) Called each time there's a change in the size of the video being rendered.

Method Detail

onVideoSizeChanged

void onVideoSizeChanged(int width,
                        int height,
                        int unappliedRotationDegrees,
                        float pixelWidthHeightRatio)

Called each time there's a change in the size of the video being rendered.

Parameters:

width - The video width in pixels.

height - The video height in pixels.

unappliedRotationDegrees - For videos that require a rotation, this is the clockwise rotation in degrees that the application should apply for the video for it to be rendered in the correct orientation. This value will always be zero on API levels 21 and above, since the renderer will apply all necessary rotations internally. On earlier API levels this is not possible. Applications that use TextureView can apply the rotation by calling TextureView.setTransform(android.graphics.Matrix). Applications that do not expect to encounter rotated videos can safely ignore this parameter.

pixelWidthHeightRatio - The width to height ratio of each pixel. For the normal case of square pixels this will be equal to 1.0. Different values are indicative of anamorphic content.

onRenderedFirstFrame

void onRenderedFirstFrame()

Called when a frame is rendered for the first time since setting the surface, and when a frame is rendered for the first time since a video track was selected.
